Significant Points Many physicians and surgeons work long, irregular hours; more than one-third of full-time physicians worked 60 hours or more a week in 2006. Acceptance to medical school is highly competitive. Formal education and training requirements are among the most demanding of any occupation, but earnings are among the highest. Job opportunities should be very good, particularly...

Pain is a universally-understood sensation of discomfort, distress, or agony that results from stimulation of specialized nerve endings. It serves as a protective mechanism in that painful stimuli often coincide with tissue damage. Avoidance of pain is a powerful survival mechanism, and the motivation to avoid pain is as deep-seated as are the drives to obtain food and reproduce. It is defined...

Americans spend a great deal of time on their feet. As the Nation becomes more active across all age groups, the need for foot care will become increasingly important. Nature of the Work The human foot is a complex structure. It contains 26 bones—plus muscles, nerves, ligaments, and blood vessels—and is designed for balance and mobility. The 52 bones in the feet make up about one-fourth of all...

Significant Points Job opportunities should be very good. An associate degree is the minimum educational requirement, but a bachelor’s or master’s degree may be important for advancement. All States, except Alaska and Hawaii, require respiratory therapists to be licensed. Hospitals will account for the vast majority of job openings, but a growing number of openings will arise in other se...
